NORTH FORK, NY — A teen with North Fork roots took the stage on Sunday with superstars, performing with Kenny Loggins during the “Concert Across America to End Gun Violence” at the Arlington Theater in Santa Barbara, California.

Artists and activists came together for the event, which also included Christopher Cross, Zach Gill of ALO, Venice, Michael McDonald, Ozomatli, and Venice — and Jackson Gillies, who had deep ties to the North Fork.

Jackson was diagnosed at three years old with Type 1 diabetes and he has also battled Hidradenitis Suppurativa; HS is related to leaky gut.
